Satellite directly sees 'Sun-quakes'

Listening to the Sun through a technique similar to seismology opened a new era for understanding the Sun's interior. The French Space Agency's (CNES) and the European Space Agency's (ESA) COnvection ROtation and planetary Transits (COROT) satellite applied this technique to three stars, directly probing the interiors of stars other than the Sun for the first time.When scientists discovers the Sun's global oscillations, they opened a window to the Sun's interior. Just as the propagation of seismic waves on Earth provides information about our planet's interior, sound waves travel throughout the Sun carrying information about what is happening below the surface.
